TRIPLE-BALANCED MIXERS M2-2 Page 4 LO/RF 2. to. GHz IF.4 to. GHz Downconversion Spurious Suppression Spurious data is taken by selecting RF and LO frequencies (+mlo+nrf) within the 2 to GHz RF/LO bands, which create a 2. GHz IF spurious output. The mixer is swept across the spurious band and the mean is calculated. The numbers shown in the table below are for a -1 dbm RF input. Spurious suppression is scaled for different RF power levels by (n-1), where n is the RF spur order. For example, the 2RFx2LO spur is 2 dbc for a -1 dbm input, so a -2 dbm RF input creates a spur that is (2-1) x (-1 db) db lower, or 62 dbc.

An LO which is 2. GHz higher than the RF is used to create a 2. GHz reference IF. A second LO is used to create a 2x2 spurious IF, also at 2. GHz (1. GHz fundamental IF). The difference between these two output levels is the spurious suppression in dbc. The mean value across the 2 to 48 GHz RF input band is the number shown in the table above. -1-2 -3-4 - -6-7 -8 2RF x 2LO Spurious Suppression (dbc) RF Input Frequency (GHz) Downconversion 2RFx2LO Spurious Data Example: RF Input: 2 to 48 GHz @ -1 dbm LO for Reference: 4 to GHz LO for Spurious: 3 to 49 GHz IF Output: 2.

TRIPLE-BALANCED MIXERS M2-2 Page LO/RF 2. to. GHz IF.4 to. GHz Upconversion Spurious Suppression Spurious data is taken by mixing a 2. GHz IF with LO frequencies (+mlo+nif) which create an RF within the 2 to GHz RF band. The mixer is swept across the spurious output band and the mean is calculated. The numbers shown in the table below are for a -1 dbm IF input. Spurious suppression is scaled for different IF input power levels by (n-1), where n is the IF spur order. For example, the 2IFx1LO spur is typically 47 dbc for a -1 dbm input, so a -2 dbm IF input creates a spur that is (2-1) x (-1 db) db lower, or 7 dbc.

A 2. GHz reference IF input is used to create an RF output that is 2. GHz below the LO input (LO-IF=RF). A second LO (2. GHz higher) is combined with the same 2. GHz IF input (LO-2xIF=RF) to create the same 2 to 46 GHz RF output band. The difference between these two output levels is the spurious suppression in dbc. The mean value across the RF output band is the number shown in the table above. -1-2 -3-4 - -6-7 -8 2IF x 1LO Spurious Suppression (dbc) RF Output Frequency (GHz) Upconversion 2IF x 1LO Spurious Data Example: IF Input: 2.
